Time Delay Relays
Dedicated - Single Shot
TDUS SERIES
Single ShotTimer
Description
TheTDUS Series combines digital timing circuitry with universal
voltage operation. Voltages of 24 to 240VAC and 12 to 24VDC
are available in three ranges. TheTDUS Series offers DIP switch
selectable time delays ranging from 0.1 seconds to 102.3
minutes in three ranges. Its 1A rated output, ability to operate
on multiple voltages, and wide range of switch selectable time
delays make theTDUS Series an excellent choice for process
control systems and OEM equipment.
Operation (Single Shot)
Input voltage must be applied before and during timing. Upon
momentary or maintained closure of the initiate switch (leading
edge triggered), the output energizes for a measured interval of
time. At the end of the delay, the output de-energizes. Opening
or reclosing the initiate switch during timing has no affect on
the time delay. The output will energize if the initiate switch is
closed when input voltage is applied.
Reset: Reset occurs when the time delay is complete and the
initiate switch is opened. Loss of input voltage resets the time
delay and output.
